Those Vette MAF sensors are pretty pinner.  If you're dead set on using MAF,
upgrade to a bigger granatelli or something (not that I endorse the GMS
parts).

You're using an EMS from a 245HP car with 22lb injectors, you've got to
expect that it's going to be a bit difficult.

Those who would give up essential liberty to purchase a little temporary safety
deserve neither liberty or safety. Nor, are they likely to end up with either.
